Numerical Simulation of the Aftereffect of a Co/Pt Bimodal Magneto-Optical Medium

May 15, 2002
Author(s)
Andrew P. Chen, R A. Fry, Edward Della Torre
Moving version of the Preisach-Arrhenius (PA) model function is used to simulate aftereffect in bimodal Co/Pt multilayers. The Co/Pt multilayers are assumed to have two kinds of magnetic phases, each characterized by its own magnetic properties. The Co/Pt

We summarize recent results at NIST to develop high-performance yet highly miniaturized magnetic sensors based on atomic vapors confined in microfabricated alkali vapor cells. These sensors currently achieve sensitivities in the range of a few tens of

Neutron-Scattering Measurements of Spin Excitations in LaFeAsO and Ba(Fe 0.953 Co 0.047 ) 2 As 2 : Evidence for a Sharp Enhancement of Spin Fluctuations by Nematic Order
